Four release and one rewinding machine operation program ---

First, prepare for inspection before starting the machine
1. Dust removal: Before cleaning, ensure that the work area is cleaned and there is no dust. There is no dust on the shaft. Clean it once with an air gun to remove the dust.
2, the direction of receiving and discharging: When unwinding the bar, pay attention to the direction of feeding. The discharge stick is counterclockwise. The receiving stick is clockwise.
3. The position of the gear and the position of the barrel are placed: the gear of the discharging stick and the receiving stick should be in the middle of the gear of the motor, avoiding the friction between the gear and the gear around the gear during the fine adjustment, thus causing damage to the gear or the motor; The receiving barrel should be the same on the scale of the stick.
4. Inflatable locking: After the position of the barrel is placed, use a high-pressure air gun to ventilate each barrel to ensure that each barrel is locked. (It is strictly forbidden to start the machine without inflation)
5. Induction: Manually pass the materials through the intermediate rollers and the tension sensor in sequence, and finally wrap the receiving core and fix the material head by hand. Note: Ensure that the material is neat and flat during the process of fixing the material. Put the material well and press the pressure shaft on the receiving roller.

Rewinding machine unwinding tension control system design ---

       This paper presents the design scheme of the rewinding electrical control system of the main drive for the DC motor, including the overall control scheme of the system, the control of the web unwinding tension, the control and establishment of the key quantity mathematical model and the selection of the main drive motor. type.
       Web tension control is one of the most important factors in ensuring the shape of the paper roll. The most important function of the web tension is to flatten the paper web, while the stable web tension will also avoid lateral deflection of the web. In the rewinder, the web tension is generated by the eject roller drive motor operating in the feedback brake state. The magnitude of the web tension, or the stability of the tension, lies in the control of the exit roller motor. For the tension control scheme, the control systems of domestic rewinders can be roughly divided into two categories: direct tension control scheme and indirect tension control scheme. From the control scheme, the so-called direct tension scheme uses the measured tension as the feedback signal. Compared with the given signal, the tension adjuster is used to adjust the tension. The advantage of this scheme is that the control structure is simple and the control response is rapid, but it is difficult to balance the rapidity of control response and the stability of control. The so-called indirect tension control scheme is to analyze the cause of the tension change, and compensate the main disturbance amount. If several disturbances can be controlled at the same time, good results can be achieved. Taken together, direct tension control should be combined with an indirect tension control scheme to take advantage of its fast response while avoiding other deficiencies.
       The selection of the main drive of the rewinding machine should mainly consider whether the three main aspects of the speed regulation range, power and torque of the motor meet the requirements. Of course, the cost and the coordination with the gearbox should be considered comprehensively to achieve the best cost performance. The paper gives an example of the hardware selection of the system for specific tension control requirements.

Belt rewinding machine design and working principle ---

Measure the diameter of the exit roller.
The diameter measuring sensor or the super-sonic sensor is fixed on the floor in the middle of the paper exit. The sensor measures the diameter of the reel as the reel becomes smaller in the rack position.
